IMPROVEMENT IN TREADLES FOR MACHINERY.

Specification forming part of Letters Patent No. 129,107, dated July 16,1872.

rests; R, the legs and rods upon which the treadle vibrates; X, the rodconnecting the treadle with the band-wheel W. A A are the legs or sidesof the standard which supports the band-wheel. B is a flange forming thebase of the standard, and by which it is secured to the platform byscrews or otherwise. 0 is another flange, several inches above the base,projecting out so as to hold the sorew,D, which, in conjunction with thebase B, forms a clamp by which the standard may be attached to the topor leg of a table, or any other object, by which it may be held inposition to support the wheel W.

Fig. II represents the standard and clamp combined in a reverse verticalposition and disconnected from the other parts, the same lettersreferring to similar parts in Fig. I, the

flanges B and G forming a clamp to be fastened by the screw D. E is abend made in the standard, so as to bring the wheel near the standardand yet allow the hub of the wheel to be made long to prevent wearingrapidly and make it run steadily. The standard may be made without orwith a slot, as shown by the dotted line F, to change the position ofthe wheel at option.

Fig. III represents the standard and wheel fastened to the corner of atable, N, by the clamp O and B with the screw D, and shows the bend E inthe standard A.

Fig. IV represents the standard fastened to the leg of a table, L, withthe treadle on the floor without the platform P.

I make no claimlto the treadle, connectingrod, or band-wheel, as theyhave long been in use; but

I do claim as my invention- 1. The combination of the treadle, rod, and

band-wheel with the standard 'A A upon a platform, as represented.

- 2. The construction of the standard A A with the base B and flange G,or its equivalent, substantially as described.
